Study: To receive flu shot every year will not undermine the effectiveness of children

Sunday, 28 October 2018 – Protecting a flu growth every year reduces its power to protect children?

Absolutely not, researchers say, who found that last year’s shot will not in any way reduce the flu-fighting force of this year’s shot.

The conclusion follows three years used to monitor influenza vaccine efficiency among nearly 3400 children aged 2-17 years. The researchers said that the results were strongly supporting current recommendations as children vaccinated against the flu every year. [19659002] “Even healthy children can become seriously ill and die of the flu,” warned study writer Huong McLean. She is a researcher with the Center for Clinical Epidemiology and Population Health at the Marshfield Clinic Research Institute in Wisconsin.

What’s more, “every flu season’s time and severity is unpredictable,” said McLean. “The number of children in the United States who die of flu each season ranges from about 37 to over 1

70.” In fact, the flu has already claimed the life of a child in Florida this year, she noted.

As for the idea that annual shots could in some way be overlooked, the study clearly indicated that “previous vaccination was not associated with reduced vaccine efficacy,” said McLean.

Then she added: “Get flu vaccines every year is the only best way to protect against the flu.”

The study results were published October 26th in the JAMA Network Open.

Earlier this fall, data released from the US Centers for Disease Control and Prevention revealed that last year’s flu season brought about 80,000 Americans, 183 of them children. These figures represent the death support for the highest influenza in 40 years.

CDC recommends that all Americans aged 6 months and older receive an influenza vaccine on an annual basis, with the exception of those who have allergies to one or more ingredients present in the vaccines or for those with a history of a serious paralysis called Guillain -Bear syndrome.

As regards the overall protection of the shot, the risk of a child’s risk of dying by more than half (51 percent) of the CDC is reduced by a child. It reflects data covering four influenza seasons ranging from 2010 to 2014.

For the most recent survey, about half of the children’s participants – at an average age of almost 7 – received one of two types of flu shots 2013: either the live attenuated flu vaccine or the inactivated flu vaccine.

In the end, the team observed that children who had also been vaccinated the year before 2012 ended with a stronger LAIV protection against a type of flu, H3N2, 2013, compared to those who had not been vaccinated during the previous year.

LAIV protection against another influenza type, H1N1, was not affected in one way or another by previous vaccination stories, according to the report.

And the children who had received influenza in the previous year in 2012 did not affect the protection strength of their 2013 IIV shot, with respect to both types of flu.

The same influenza-shot efficiency pattern continued to evolve in the next two-influenza seasons, the investigators found.

While encouraging parents to talk to the pediatrician if they have any questions or concerns, McLean emphasized that “the flu vaccine is safe for children and adults.”

And since it takes a couple of weeks for protection to catch after shooting, she noted that “parents should have their children vaccinated as soon as possible so that they are protected before the flu season begins.”

Dr. Alicia Fry is the head of the CDC’s epidemiology and prevention branch. She said that the latest study is one of a few to specifically look at influenza vaccine in children year after year.

The results “are calming and support current flu vaccination,” said Fry.

Getting an influenza vaccine has proven to be a life saving tool for children. CDC recommends that annual influenza vaccination is still the first and most important step in protecting against the flu and its complications, “Fry added.”
